Naughtology Sandwich Dual Form Nail Kit — 360 pcs Coffin & Almond, 15 Sizes, Reusable Plastic

The Naughtology Sandwich Nail Dual Form Kit is a complete 360-piece set of reusable top-and-bottom dual forms designed to make consistent coffin and almond nail extensions quickly and cleanly with polygel, acrylic, or builder gel.

Whether you’re an at-home nail artist or a busy salon technician, this kit provides two full shape options, 15 sizes each, and numbered storage boxes for rapid size selection. The sandwich design pairs a matching top and bottom form to cradle product during curing, reducing overflow and finishing time. Built-in length scales and reusable plastic construction help you create repeatable, salon-grade extensions without complex sculpting skills.

How does the sandwich design simplify nail extension application?

The dual top-and-bottom forms lock together around your chosen product to shape the extension as it cures. This removes the need to free-form sculpt, reduces surface defects, and makes thickness consistent across nails.

• Top and bottom shells align to capture product evenly.
• Pre-shaped interiors create uniform curvature and apex.
• Marked length scales let you set identical lengths across fingers.
• Reusable plastic eliminates one-time form waste.

Which shapes and sizes come in the kit, and how are they organized?

The kit contains 360 pieces total: 180 coffin dual forms and 180 almond dual forms spanning 15 sizes. Each shape is stored in its own box with 15 numbered compartments, so you can find the exact size quickly during a service.

• 15 size gradations per shape for small to long extensions.
• Each compartment holds 12 pieces (6 top, 6 bottom) for repeat use.
• Clear numbering avoids guesswork when matching natural nails.
• Boxes keep forms organized and protected between uses.

Can I use these dual forms with polygel, acrylic, and builder gel?

Yes. The durable plastic dual forms are compatible with polygel, acrylic systems, and builder gels; the sandwich technique works for any viscous product that cures or sets inside the form. Because the forms enclose the product, you’ll see less flooding and fewer bubbles than with freehand sculpting.

• Polygel: ideal for controlled shaping and easy removal from the form.
• Acrylic: use the forms to set quick, consistent lengths and profiles.
• Builder gel: contains the gel during curing for a smooth finish.
• Works with LED/UV curing and air-set systems depending on product.

Who is this for: Nail enthusiasts who want repeatable, professional-looking extensions without advanced sculpting, salon techs needing efficient, organized kits for high-volume work, and beginners learning extension techniques. If you value time-saving tools, consistent results, and two popular shapes—coffin and almond—in a single reusable kit, this set is a practical choice.
